HEATING UTENSIL.

SPECIFICATION forming part of Letters Patent No. 577,896, dated March 2, 1897. Application filed October 29, 1896. Serial No. 610,428. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. WALKER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Heating Utensils, of which the following is a specification.

My invention relates to an improved heatin g device adapted to be sustained on the top of a lamp or other chimney, and will be fully and clearlyhereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 represents an inverted plan View, one of the spring-arms being folded against the utensil-base. Fig. 2 is a side elevation showing the device attached to a chimney. Fig. 3 represents also an inverted plan View showing a modified construction of the device. Fig. 4 is a side elevation of the construction shown in the said Fig. 3. Fig. 5 is a detached detail modification of one of the supporting portions.

My invention is designed to be supported on the top of the chimney, and is held thereto by a series of spring-arms projecting down into the top orifice of the chimney and press-' ing outward against the interior surface of the same. For convenience in packing the arms are constructed so as to fold down against the utensil-base. The said arms are also separably connected to the said base, so that they may be removed therefrom if required.

Referring to the drawings in detail, 1 represents the utensil-base, which is preferably constructed of sheet metal. It is provided with the usual central circular draft-opening 2. The spring supporting-arms 3 are construoted in substantially the shape and form shown in Figs. 1 and 2', and are hinged or pivotally connected to the utensil-base by the supporting portions 4. These supporting portions may be fastened to the utensil-base by the clamping means shown in Fig. 1, or they may be secured in any Well-known way.

I11 the method shown in Fig. 1 the clamping-ears 5 are stamped and cut in the utensilbase itself and are integral therewith. These clamping-ears are adapted to fit in the slits 6 and are turned or bent down upon the supporting portion, thus securing it to the utensilbase.

It will be noticed by reference to Figs. 1 and 2 that each supporting portion is provided with a downward-extending portion 7, which rests on the chimney-top. The object of these portions 7 is to elevate the utensil above the top of the chimney sufficiently to allow an air-space between the said chimneytop and the bottom of the utensiLbase. A locking portion 8 is stamped and cut from the utensiLbase, (see Fig. 1,) or it may be formed on the supporting portions. The object of the locking portions is to provide means for rigidly holding the supportingarms in their depending position when in the chimney. This object is attained by bending the ends 9 of the supporting-arms at or about the point 10 at about a right angle thereto, so that the said ends can fit under the looking portions and be held between the said locking portions and the utensil-base.

The pressure exerted against the sides of the supporting-arms when they are sprung into the mouth of the lamp-chimney and the utensil is properly placed on the top of the said chimney tends to force the said ends under the said locking portions, and thus antomatically lock the said supporting-arms with a spring force in their proper depending position.

In Figs. 3 and 4 I have shown a modified construction of the device, the downward extending portions '7 of the supporting portions 4 being done away with and the supporting-arms provided with additional bends to act in lieu thereof. The hinge portions of the arms in this construction can be easily removed from their sockets and the supporting-arms separated from the utensil-base. In separating the supporting-arms from the base in my preferred construction, as shown in Figs. 1 and 2, I am obliged to release the ears 5 from the slits 6. As in some instances a more convenient means of separating the said arms from the base may be required, I have shown a modified construction of a supporting portion in Fig. 5. In this construction the supporting portion is formed of spring material and is secured to the base at the points 11, and on one side only, and the hinge portion 12 of the supporting-arms is adapted to spring into and out of the said supporting portion on the opposite or unsecured side.

The operation of the device will be easily understood from the drawings and the foregoing description.

This device is adapted to be used in either a straight or a curved flaring-mouthed chimney.

I claim as my invention- 1. The combination with a chimney, of a heating utensil comprising a base portion and a series of hinged spring supporting'arms depending therefrom, and locking devices so arranged on the base portion that the said supporting-arms are automatically locked in their proper depending position, when sprung in the chimney-mouth.

2. A heating utensil, adapted to be attached to a lamp-chimney, comprising a baseplate, and a series of supporting-arms hinged thereto and provided with bent ends for limiting their pivotal folding or unfolding movement to or from said base.

3. A heating utensil consisting of a utensilbase, spring supporting-arms, and supporting portions or clamping-hinges for hinging and securing said arms to said base.

4. A heating utensil, consisting of a utensilbase, spring supportingarms, supporting portions or clamping-hinges for hinging and securing said arms to said base and a series of depending portions for elevating the said base and thereby forming air or draft spaces between the chimney-top and the bottcm of the utensil-base, as set forth.

5. A heating utensil, adapted to be attached to the top of a lamp or other chimney, consisting of a base-plate, a series of spring supporting-arms hinged thereto and adapted to press against the interior surface of the chimney, and devices for locking them with a spring force in their depending position when the utensil is attached to the chimney-top.

6. The combination of a utensil-base, clamping-ears stamped therefrom and formed integral therewith, clamping-hinges, slits in said hinges through which the said clamping-ears are passed and folded down and thus fasten the said clamping-hinges to the utensil-base, spring supporting-arms fastened in and depending from said clamping-hinges, and locking-ears also stamped from the said base for securely holding the arms in their downward depending position when the said arms are pressed against the interior of the lamp-chimney, substantially as described.

7. The combinationwith a chimney, of a heating utensil, consisting of a utensil-base, spring supporting-arms hinged to the said utensil-base, said arms being adapted to fit in the chimney-top and press outward against the interior surface of the said chimney, and locking-ears whereby the said arms are rigidly held in their position when the utensil is secured to the chimney, as set forth.

8. A heating utensil, adapted to be attached to a lamp-chimney, comprising a baseplate and a series of spring supporting-arms hinged and detachably secured thereto, the said arms being immovably locked in their proper depending position when the utensil is attached to the chimney, but removable therefrom when the utensil is not located on said chimney.

9. A heating utensil, adapted to be attached to a lamp-chimney, comprising a baseplate and a series of supporting-arms dependin g therefrom and adapted to fit in and press outwardly against the interior surface of said chimney, the said arms being unremovably secured to said base-plate when the utensil is attached to the chimney, but capable of detachment therefrom when the utensil is separate from the said chimney.
